  • Page 3 Address: Dieselstrasse 8 D-77815 Bühl (Baden) hereby declares that the product: Data Receiver Type IoT Box with all options complies with the following harmonized standards: EN 61000-4-2, EN 61000-4-3, EN 61000-4-4, EN 61000-4-5, EN 61000-4-6, EN 61000-4-11 according to directive 2004/30/EU (electromagnetic compatibility)
  • Page 4 In this technical manual you will find the necessary information for installation & operation of the IoT Box. ► Read this manual before operating the product. This will protect you and prevent damage to your device. ► Always keep this manual in a place where employees, service personnel, etc. can view it. Present this manual to the inspector or the contracted specialist company at each recurring inspection.
  • Page 5 To avoid exposing yourself to the risk of electric shock, do not remove the housing cover. There are no user-repairable parts inside the unit. Leave repairs to the qualified EHP customer service. There is a risk of contact with non-insulated parts inside the device, which can lead to electric shocks.

  • Page 11 Depending on the installation location of the IoT Box, different cable lengths are required. Therefore, only the connector for the power connection - Neutrik Powercon NAC3FCA - and the connector for the network connection - Neutrik Ethercon NE8MX - are included in the scope of delivery.
  • Page 12 This completes the commissioning on the hardware side. The IoT Box has a radio range of up to 500m in the open field. Obstacles between the scales and the IoT Box, such as walls, can impair the range accordingly. Therefore, if possible, select a location with a clear view of the connected scales.
  • Page 13 This facilitates the integration of the Netscale in order to be able to use commands such as "Register weight – 10 without any programming effort or to establish communication with an EHP large display if no permanent IT connection of the network interface is provided.
  • Page 14 The SD-Card can easily be exchanged by pushing on it. It’s located at the top of the NetScale.
  • Page 15 Using the predefined GSDML & UDT files, you can integrate the IoT Box into your PLC network in just a few steps. You can obtain the files from your EHP contact. The following describes the integration of the relevant information in the widely used TIA Portal (TIA Portal is not part of the IoT Box scope of delivery).

  • Page 23: Weight Information

    The following information is displayed: 1. Scale information Scale Name, the actual weight and the scale status (stand still) are shown. With the cursor symbols at the left and right you can select other scales. 2. Weight information Tare weight , Gross weight & registered weight are shown 3.
  • Page 24 The EHP crane scale must have a release version LAH12.26 or LAH12.42 to operate with IoT- Box.As standard only scales are integrated which are purchased together with the IoT-Box. For the integration of existing scales please contact your EHP contact person.
  • Page 25 The Net-Scale protocol requires that the scale and channel numbers match. You can only receive data from a scale if both values of the scale are identical with the call-up commands of the Net-Scale. ► Press the TEST key of the crane scale, the most important setting parameters are now displayed one after the other.
  • Page 26 Activate the parameter using the tare key to call up the position to be changed. Use the Test key to enter a value between 01- 28 (corresponds to channel 01-28). Close the parameter with the zero key. Press the Test key repeatedly until P14 (scale number) appears in the display.
  • Page 27 First press the tare key and then operate with the zero key Sto (Store) flashes in the display. To exit the setting mode, press the On and Off keys simultaneously or briefly disconnect the scale's battery pack Table 5 - Change frequency & scale number...
  • Page 28 EHP scales that already have the corresponding radio equipment can be connected directly to the IoT box. If your EHP scales do not yet have radio equipment, this can be retrofitted at low cost. If your scales are equipped with the appropriate radio technology, they can be connected to the IoT box without any problems.
